Photodynamic therapy (PDT) is a ground breaking medical technique which uses lasers to activate light-sensitive chemicals to treat cancer and other diseases without resorting to surgery. For the first time, Chemical Aspects of Photodynamic Therapy introduces in an accessible way the physics, chemistry and biology behind the technique. This highly authoritative account of the account of the rapidly developing field of PDT explores its chemical basis, while presenting information in its historical context. Haematoporphyrin derivative is considered in detail, together with the new 'second generation' photosensitisers , such as chlorins, bacteriochlorins and phthalocyanines. Photosensitisers which are currently in clinical trials are compared and reference is made to new light sources, biological and clinical findings, and prospects for future developments. This book is essential reading for new students and researchers alike studying PDT. It is recommended particularly for photochemists, as well as photobiologists and clinicians. About the author Raymond Bonnett was born in London in 1931. After a spell in the air force, he graduated from Imperial College, going on to Cambridge to research under Alexander Todd and A.W. Johnson and then to Harvard to work with R.B. Woodward. He is now Scotia Research Professor of Chemistry at Queen Mary and Wesfield College, University of London, UK. He has been active in research on photosensitisers for 25 years and has published over 200 papers on the chemistry of porphyrins and related compounds.

The main objective of this book is to present the recent applications of photodynamic therapy (PDT) in treating cancer and other diseases. The limitations associated with current PDT agents, and the synthetic designs that have been used in various laboratories are also discussed. The utility of certain tumor-avid agent for cancer imaging (fluorescence, PET, MRI) is also summarized. The book also includes the use of delivery vehicles, including nanoparticles in improving the tumor-specificity of the desired agents. The book is basically focused on the translational approach of drug development. By providing certain specific examples, a clear concept of moving a 'product' from the bench to bed-side is also discussed.To have a clear concept of drug development the book is divided in three parts — Medicinal Chemistry, Mechanistic and Clinical studies. Each part includes the contributions from the leading scientists with extensive experience in the respective field. The handbook is assembled by renowned scientists Dr Dougherty, known as the father of PDT, Dr Kessel, well known for his contributions on mechanism of PDT and Dr Pandey for his inventions in developing improved agents for PDT and cancer-imaging.

Today, in the face of resistant microorganisms, aggressive cancers unresponsive to conventional treatments, and the COVID-19 pandemic, the need for advanced and innovative protocols for combating and treating disease is paramount. This book presents basic concepts of photodynamic therapy along with data from clinical research on its use in treating oncologic and other diseases. It also presents innovative strategies in photodynamic therapy, including information on polymer nanoparticles. This book was prepared with great care and by many valuable hands so that we can expand the dissemination of Photodynamic Therapy, as well as motivate for new research.

Certain organic compounds can become toxic to biological tissue when activated by light. Many medical applications of this effect have been studied over the past twenty years, and This symposium brings together chemists, biologists, and clinicians to discuss the basic chemistry of the sensitizing compounds, their biological effects, and clinical applications in treatments of various cancers and skin disorders.

As a new concept of cancer treatment, photodynamic therapy (PDT) has gained great attention in the last few decades. Compared to classical treatments such as surgery, chemotherapy and radiotherapy, PDT is a noninvasive, localized treatment of lesions that shows fewer side effects and has low systemic toxicity. In Chapter One, the basic mechanisms, applications and functional nanomaterials-based drug delivery systems for photodynamic therapy of cancer are reviewed. Chapter Two summarizes the application of different carbon based nanomaterials as agents for PDT and discusses current state-of-the-art use of fullerenes and their derivatives, carbon nanotubes and graphene quantum dots in PDT. Chapter Three covers the benefits and pitfalls of using chemi- and bioluminescent systems as intracellular excitation sources in PDT. Bioluminescence is a widespread natural phenomenon, which consists on emission of light resulting from the oxidation of a substrate in a reaction catalyzed by an enzyme in a biological system. Chapter Four addresses in the synthesis, characterization, and photodynamic activity of a novel hydrophobic photosensitizer 5,10,15,20-tetrakis(benzo[b]thiophene) Porphyrin (BTP) and water soluble photosensitizer 5,10,15,20-Tetrakis(7- sulfonatobenzo[b]thiophene) Porphyrin (SBTP). The authors lab is engaged in the synthesis of PDT molecules incorporating benzothiophene moiety to the meso-position of porphyrin molecules. Chapter Five discusses the Guidelines for Gastroenterological Endoscopy in Patients on Oral Antithrombotic Treatment established by the Japan Gastroenterological Endoscopy Society (JGES).These guidelines classify endoscopic interventions according to the risk of hemorrhage and specify the management of various antithrombotic drugs. Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are classified as high-risk procedures for hemorrhage, but PDT is not included in the guidelines. Because PDT causes ischemic necrosis of tumor tissue, the authors say this could possibly be performed safely in patients on oral antithrombotic therapy. The authors of Chapter Six developed a method of the initial concentration of protoporphyrin-IX in the operated removing glioblastoma tissue using the calibration curve of the fluorescent intensity and the known Pp-IX concentration in order to estimate of the more correlated with the cure rate.

Comprehensive Series in Photochemical and Photobiological Sciences. Photodynamic therapy (PDT) is increasingly being used amongst health practitioners in combating a variety of disease. This book reviews the current state of development of PDT, and also presents the foreseeable advancements of the field in the next decade. Practitioners in biological sciences, biotechnology and medicinal and pharmaceutical chemistry will find this book an invaluable source of information. Chapters are drawn from research discusses at the 10th International Symposium on Photodynamic Therapy and Photodiagnosis in Clinical Practice in Brixen and are written and edited by leaders in the field. Mirroring the philosophy of that meeting, this book contains an informative balance of the basic sciences and clinical applications of PDT. Following an introduction to PDT, its history, and how techniques have developed, chapter serve as a practical guide for practitioners, covering topics such as sensitizer dosage and light dosage, and examples of relevant studies. The text goes further tp explore areas outside the medical field, such as the impact of PDT on society and the environment, and the economics of therapies. This book is dedicated to the memory of Professor Giulio Jori, and expert in this field, who sadly passed away on the 23rd December 2014.
